Key Moments
- Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson fires the home side ahead with a well-placed effort in the second half.
- Matheus Cunha responds just three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a through ball from introduced the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a combination of injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's options.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not completed yet but step by step, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
